text: There are different spectroelectrochemical techniques based on the combination of spectroscopic and electrochemical techniques. Regarding electrochemistry, the most common techniques used are:
  *Chronoamperometry, which measures current intensity as a function of time by applying a constant difference of potential to the working electrode.
  *Chronopotentiometry, which measures the difference of potential as a function of time by applying a constant current.
  *Voltammetry, which measures the change of current as a function of the linear change of the working electrode potential.
  *Pulse techniques, which measure the change of current as a function of difference of potential, applying pulse potential functions to the working electrode.
  The general classification of the spectroelectrochemical techniques is based on the spectroscopic technique chosen.
